The morphology of two strains of Penicillium chrysogenum immobilized in calcium alginate and used in penicillin fermentation was examined. The degree and distribution of mycelial growth inside and on the surface of the beads depended on the strain, the cultivation media and the fermentation time. P. chrysogenum ATCC 12690 developed as a mycelial network inside the beads. The growth tendency of P. chrysogenum S1 in micropellets was directed to the outer surface of the beads. At the end of the… CONTINUE READING
